difficult child has never been formally tested privately or by the school. He's currently on a 504 only. I'm having him privately tested over the summer, then will address the school to place him on an IEP. I know they may not consider the private testing I am having done but it's more for my piece of mind in understanding how best to help him via psychiatrist, social classes, etc. The testing is being done by a major medical hospital in my area and will run approx. $3k, although most may be covered by my insurance (first thing they do is call the insurance and determine coverage, pre-cert, etc). I was told that after they get the insurance information, they will call me back and ask a few questions to determine what testing needs to be done. What should I take into consideration? My biggest concerns are behavioral and determining a diagnosis so we can get his medication on the right path (he is not responding well to what he's on and I'd like to no longer play russian roulette with his brain chemistry). Any suggestions on what I should consider / ask / do / etc??
